We don't just build our custom twin turbo systems, we install them, too! UPP has a fully-staffed performance shop nestled at the foot of Pike's Peak in Colorado Springs, Colorado. Our driven team is dedicated to making your power goals a reality. While we specialize in LS-based performance, many of our technicians also have extensive experience in Japanese sports cars. Don't want to install yourself? Want a kit for a vehicle not listed on our site? Or would you like to lay out the groundwork for your next engine swap? Give us a call, and we'll steer you in the right direction!



We tune in house on a Dynocom AWD Dynamometer capable of measuring 1800+WHP per axle. Our dyno features twin Eddy load absorbers and can bring a 600WHP car to dead-stop at wide open throttle. Need a baseline or a full tune? UPP has you covered either way! We stand by our numbers, and will never manipulate our dyno. 

Our full dyno tunes are by appointment only, as we want to spend as much time with your vehicle as necessary to help meet your goals. Give us a call today for pricing and availability!



We pride ourselves on our quality craftsmanship. Our experienced, in-house fabricators can design and build anything from intercooler piping to a full tube-frame chassis. Whether it be a simple fix on a cracked manifold or a custom exhaust for your race car, we have the experience and resources to build whatever you need! Contact us today to set up a quote.
